This document summarizes the changes to the module between releases.
## release (EPICS 7.0.2.2 April 2019)
Changes have been made for getDouble, putDouble, getDoubleArray, putDoubleArray, getString, putString, getStringArray, and putStringArray.
1) Previously each only had support for a top level field named value.
Each now allows access to a single sub field that has the correct type.
Thus pvRequest must select a single field. For example
pva->channel("PVRdumbPowerSupply")->putDouble(1.0,"power.value" );
2) PvaChannel now has a method for each of the above.
For example instead of
PvaClientChannelPtr channel = pva->channel("PVRdouble");
PvaClientPutPtr clientPut = channel->put();
PvaClientPutDataPtr putData = clientPut->getData();
putData->putDouble(1.0); clientPut->put();
now it can be
pva->channel("PVRdouble")->putDouble(1.0 );
3) getDoubleArray and putDoubleArray work with any numeric scalar array
4) getStringArray and putStringArray work with any scalar array.
## Release 4.4 (EPICS 7.0.2, Dec 2018)
